Specification of Letters Patent, estimation filed March 22, 1906. h M1No. 807,480.

. Patented Oct. so, 1906.

To all whom it mag concern:

Brooklyn, in the county of Kings and State" of New York, have inventednew and'useful Im rovenients in Rotary Steam-Engines, of

is a specification.

. This invention a lows accurate adjustment of bearing to be madefromthe outside of the k pt ple construction.

Fig. 5 is a section alo device, so that effective packing can bemaintained.

ator therefor, the valve being arranged to be '11 accurate alinement andbeing of sim- This invention isset forth in the fol owing specificationand claims, and illustrated in the annexed drawings, in which v Figure 1is asideelevation ofa deviceem-' bodymg this invention. Fig. 2 showsparts of Bi 1 in section, 3 is a section along a: z, ig.'j1. Fig. 4shows a drum and pistons. t i x In the drawings is s own a cylinder awith c'overor head "Asuitable ground joint be- ,plate enables-tight fitor closure te be made. 11 the cylinder 1s, a' rotary drum 0, having e rm he ds "b. As thishe'ad is'adi S b, the drumcan be; th reby s t uste'dfor its pistons'd'to close or suitably piece f having an-inclined face.A's the nut g at said piece isloosened andthe screws h turned in theproper direction, the adjuster f is moved to ra1se or set the head. 1

a The cylinder has dowel or dguide pi'ns 'i, and the cover by suitableslotte 'p from the packing. The holes in the cover forelongated-adjustment will be possible. 'T edrum c is shown with pistonsd,having I. rods n. These rods are hollow and are practi I ,cally castor forged with the pistons.

The

: rods coming from opposite plstons slide or .tlescoprinto one another.Entrances or holes 0 allow pressure to enter to spread the rods orpistons" and hold the latter or the packing p to' the cylinder. Theentranceports o have valves or balls g, which at suit tweenfthe cylinderand its head or cover-- I have a' governor 14 of sui ,cOntact at packinga. A certain wear can :thus be compensated for. 'Thisv-hea'd b is shownsupported at one, part by anadj-ustingarts straddles .pins'i, so thatthe cover'is' guided vertically or adjusts along a ,detell'ninndline or.to and able intervals close the holes 0 to prevent escape of pressure,but allow entry of pressure into the sliding stems or-pistons.

The pistons have packings consisting of suitable plates 1", held bpressure through branches 8 from the ho] owpiston-stems to the seats inthe drum. At these seats are jplates t of suitable material and havingofi sets or shoulders resting in corresponding ,oflfsets or depressionsin the piston-seats in the drum or in the walls of the recesses in whichthe pistons play. On-dismounting the piston the lining-pieces f can beremovedor exchanged.- J i The steam or working pressureis 'allowedto-enter at suitable intervals through valve 2.

This valve is actuated by a cam 3 at suitable intervals. The valve has astem with antifriction-roller 5-touchin'g the cam. 1

- A sprin .6 is braced against cap 7 of valvecase 8, an this springtends to hold the valve closed. The stem 9 of the valve has a clamp '10held thereto by' tightenin screw 11.

This clamp .carries pins 12-, whic are guided in recesses or ways lnthevalve case or cap 7. The guide-pins prevent the valve being turned 01'the antlfric'tion-roller coming into wrong position. In other words,"the axis of the roller and that of the'cam are to be parallel.

The steam or pressure-su ly pipe 13 can table construction. Thetransmission of motion between drum 0 and cam 3 by only two gears wouldmake cam3 rotate in the opposite direction to that of the drum, which inthe particular construction shown would not interfere with theoperation; but a different number of transmission-gears or differentcam-actuation can be provided to change the direction of rotation of thecam or arrange the'movements as desired or called for. l

What'I claim as my invention, and desire to secure by Letters Patent,is-' ,1. An engine-cylinder and head ad'ustably connectedto thecylinder, guides on t ecylinder for the head an adjusting blockvor piececonnected to the cyllnder and adjustingscrews for setting the block toadjust the head. l

2. An engine having a cylinder with drum,

and pistons for the drum, said pistons having stems which are hollow toadmit pressure from the interior of the drum for holding the pistons inposition.

3. All engine-having a cylinder *withdrumand pistons, and hollowpiston-stems having vents for allowing the entry of pressure to v spreadthe pistons;

4. An engine having a cylinder with drum and pistons, hollowpiston-stems made-to-'tele scope in one another, and means for su plyingpressure into the stems to sprea the pistons.

5. An engine having pistons with stemssuitably chambered for the entryof pressure, said stems having ventsand 'valves-for-closing the vents atsuitable periods.

6. A cylinder with drum and pistons; and

a packing between" the drum and pistons, said pistons having apressure-ventatftl're packing to cause the packing to make tightclosure. i

7. A'cylinder with drum, pistons cast with.

hollow stems in the drum, and: means for'admitting pressure intothestemsfor s reading the pistons to contact with the'cylin r;

8. A cylinder comprising a rotary drum with recesses-having ofi'sets;interchangeableto the-piston, and a valve-actuating cam having actingfaces corresponding to the pistons.-

10. An engine having a valve with actuating-cam therefor, said valvehaving a stem with a clampcarrying guideins.

- 11. An engine having a va ve with actuatingrcam therefor, said valvehaving, a stem with a clamp carrying guideins, and a friction-rollerheld in line with t e cam by said pins.

12. An engine having a valve-actuating cam, avalve' with -a stem; ahousing for 'the valve; pins guided'by' the "housing, and" a: clamp forsecuring thepins to the-stem:

13; An engine-e linderandh'ead; aguide for the-head,' a settinblook'ha-vin'g one of its faces beveled',-and*" meanewfor adjusting theblock.-' I v 14. An engine-cylinderwith a movable head having aninclined portion", asetting block with a correspondingly-inclinedface-to engage'the head, and means for adjusting the block.

'In testimony whereof- I havehereunto set my hand in the presence of twosubscribing witnesses.
